Purpose: This study looks at people with low back pain (LBP) to see who might feel better with a treatment called Intramuscular Dry-Needling (IMDN). IMDN is a technique where thin needles are inserted into muscles to help reduce pain. The study aims to create a tool to help doctors decide who will benefit from this treatment.

Study Details: The study has two parts. In the first part, participants are randomly divided into groups to receive either real or fake (sham) needling, along with exercises. They will be checked several times to see how pain changes. The second part will analyze the data to find patterns and predict who benefits from IMDN.

• Study Length: Involves multiple visits over a few weeks.
• Participation: Open to adults 18-60 years with non-traumatic low back pain, but you can't join if you’re pregnant or have had certain surgeries.
• Risks: Possible discomfort from needling; all participants also do stretching exercises.

Note: Only people who can speak and read English and have a BMI under 35 can participate.
